A wearable device to assist fingering function for disabled is developed in this study. This is the second paper to report the progress in development of this assisting device. The device is developed for a patient who suffers from cervical spinal cord injury. In the first paper, it was reported that the patient could successfully pick up several types of objects with his paralyzed fingers by using this device. As a next step, the maneuverability of the device under grasping operation is discussed in this paper. Maneuverability of the system is experimentally evaluated. The dexterity in controlling finger force is compared between the cases that non-disabled examinees operate their finger with inherent abilities and that a disabled examinee operates his finger by using the assisting device.

As cities develops, road systems become more and more complicated. These days people depends on navigation systems when walking as well as driving cars. General navigation systems are either installed in cars or exists as smart phone applications. Therefore, it is very difficult to use them while walking or riding bicycles. Moreover, disabled person cannot use them to find his destinations. In this paper, we propose a bracelet navigation system for walkers and disabled people, and describe the design and implementation of such a device. This navigation will help not only walkers and people riding bicycle but also disabled people to actively participate their social activities.

A new type of wearable robot is developed for a disabled person with disabled limbs, that is, a person who cannot intentionally move his/her legs and arms. This robot can enable the disabled person to grip an object using eye movements. A gaze tracking algorithm is employed to detect pupil movements by which the person observes the object to be gripped. By using this gaze tracking 2D information, the object is identified and the distance to the object is measured using a Kinect device installed on the robot shoulder. By using several coordinate transformations and a matching scheme, the final 3D information about the object from the base frame can be clearly identified, and the final position data is transmitted to the DSP-controlled robot controller, which enables the target object to be gripped successfully.

As Korea's per capita income increases, participation in various leisure activities to improve the quality of life of the disabled is encouraged. However, in order to participate in leisure activities, movement to the place where the leisure activities are performed must be preceded, so interest in means of transportation for leisure activities of the disabled is increasing. Since manual and electric wheelchairs have their respective disadvantages as means of transportation for leisure activities, interest in power assisting devices for wheelchairs combining the functions of electric wheelchairs with manual wheelchairs is increasing. In this study, the FDA approval process of wheelchair power-assistance products was investigated, and the characteristics of side-attached, front-attached, downward-attached, and rear-attached types of power assist devices for wheelchairs wheelchair in countries around the world were identified. These information will be of great use in helping the disabled and their assistants in Korea to choose the optimal product according to the patient's condition. More usability tests and clinical case studies are needed so that people with disabilities can choose a power assist device suitable for them.

Recently, according to demands for a mobility right of people with disabilities, the use of powered mobility device has been rapidly increased and recharging facilities have been set up in many places of country. But the standards for the installation and management of the facilities are not clear and many problems are brought up in operating the facilities. Therefore, regulations and realities of recharging facilities were investigated and the user survey was progressed. On the basis of the research results, a rational and efficient installation and management plan was drawn up. The plan suggests that the recharging facilities should be installed in a building managed by government and many kinds of public building like library, theater, sports facilities, department store, museum, etc. Further, the recharging facilities should secure independent place which have specified area for protecting of privacy and provide some amenities for people with disabilities to enhance the conveniences.
